Prospects of complete feed system in ruminant feeding: A
Apr 21, 2017 · Benefits of Complete Feed System. The merits of complete feed are related to stable rumen environment for optimum fermentation with minimal fermentation losses and fluctuation in the release of ammonia, better utilization of rumen non-protein nitrogen, and stabilization of the acetate to propionate ratio which favors normal fat synthesis and enhancement of utilization of low-grade roughages [2,3].
